being provided witha ceiling A with hatchways B opening upward therethrough. The sides and ends of the car are provided with the side and end plates C and D and carlines E and purlins F constitute the skeleton frame for supporting the roof. 7.

To maintain the desired low temperature within the car, it is provided with thorough heat insulation at both the sides and above the ceiling. This prevents access to'the' roof structure from the interior of the car and therefore interferes with the repair of any roof permanently attached to thereof frame. Heretofore certain constructions of 'refrigerator cars have been provided with riveted rigid metallic roofs, but, for the reasons just stated, repair work on such roofs is difficult, involving the removal of the entire roof for the repair of'any part thereof.

With the present invention the difiiculty 192s. see-a1 its; ease;

overcome byemploying asectional metal; 11c; roof so constructed that ,anyone of the,

sections may be removed independently and therefore may ,bee'as'ily1 repairedfand re- .55 placed ;'l11 e ;o nstru@tion has thefnither ad- V vantage theta-flexible roo -is substituted for.

n Thus theindividual sheets are independently adjustable to take care of any stresses due to the weaving of the car frameand when ever it is desired to remove a sheet, this may be easily accomplished by merely the caps L.

In the portion of the roof through which i the hatch openings B extend the roofing" sheet G is apertured for the passage ofthe hatch lining and upturned flanges Gr on said 7 sheet surrounding the hatch form a weather proofjoint therewith. The hatch opening may be closed by any suitableconstruction r of lid (not shown). At the eaves the sheets Gr have downturned flanges R which are return-bent. at R to engage a return-bent flashing strip, S nailed or otherwise'secured 'to the facia P. This, while making a f thoroughly weatherproof joint, does not, interfere with the quick removal of the sheets when necessary.

In use, wheneverthere is occasion to repair any part of the roof, the defective sheet or cap is detached and either replaced by asubstitute part or may be repaired and again secured in position.

"What I claim as my invention is: I

1. The combination with a refrigerator car provided with. a ceiling, heat insulation thereabove, and a skeleton roof supporting frame, of an all-metallic eaves to ridge roof supported on said skeleton frame and formed of independently removable sections, and means accessible from outside of the said car for securing the said sections in position.

2. In a refrigerator car, the combination with a skeleton roof frame having a ceiling therebeneath and heat insulation above said ceiling, of an all-metallic eavesto ridge roof superposed on said frame'and comprising a plurality of independently removable-roofingsheets, and caps for weather-proofing and securing said sheets to the frame, and means accessible from outside of the said car for securing the said caps in position.

3. In a refrigerator car, the combination with a skeleton roof frame including cari lines and purlins, a ceiling beneath said frame and heat insulation above said ceiling, of an all-metallic eaves to ridge roof supported on said frame comprising independently removable roofing sheets having upturned return-bent side flanges, downturned flanges at the eaves and upturned flanges at the ridge, mullions secured to said roof frame intermediate adjacent sheets, Weatherproofing caps embracing said mullions and pro- 7 vided with downturned and return-bent flanges for telescopically engaging the return-bent flanges of said roofing sheets, and

' means accessible from outside of the said car for securing said weatherproofing caps and thereby retaining said roofing sheets.

4. In a refrigerator car, the combination with a skeleton roof frame, a ceiling beneath said frame provided with hatch openings 7 and lining members for said hatch openings projecting upward between .members ofjthe skeleton frame, of an--allmetall ic eaves to ridge roof overlying said frame formed of independently removable roofing sheets, and weatherproofing caps for thejoints between the sheets, and means accessible from outside of the said car for securing the said caps in position, one or more of said sheets being frame, and means accessible from; outside of the said car for secur ng the said caps 1 v in position. i

6. In a car, the combination with a roof supporting frame including side plates, of roofing sheets supported upon said frame and having upturned side flanges with.

Weatherproofing caps embracing said side flanges, brackets having a portion at the outer sides of said side plates and means for removably and Vpivotally securing said weatherproofing caps to said brackets.

In testimony'whereof I affix 'my'signatu're.
